Winter Wellness Walk

in front of the Hunnewell Building 125 Arborway, Boston

Take a brisk walk this winter and stay healthy and connected to the Arboretum at a time when the landscape is pared down to its beautiful bones. This 90-minute walk is similar to a guided tour, but with a slightly faster pace and fewer stops, to keep your feet warm and your blood pumping!

Owl Observations

Flora Way Gate (Formerly Bussey St Gate) Bussey Street Gate, Boston

Join Arboretum Horticulturist Brendan Keegan to hear about the owls’ breeding and nesting behavior, learn how to go owling ethically, and possibly hear and see a few owls as well.
